DETACHABLE BELT-COUPLING.

Application filed November 13, 1911.

'1 b all whom it may concern:

Be it known that I, JACOB BAUM, a citizen of theUnited States, residingat Cincinnati, in the county of Hamilton and State of Ohio, haveinvented certain new and useful Improvements in DetachableBelt-Couplings,,of which the following is a specification.

My invention relates to means for coupling belts to be used for variouspurposes.

The object of my invention is to provide a simple, elilcient andeconomically constructed detachable coupling which is adapted to beeasily and conveniently applied to the belt and removed therefrom whendesired and which is adapted to be readily coupled and uncoupled for thepurpose of removing, reversing or twisting the belt.

In the accomanying drawing, which serves to illustrate the construction,application anduse of my invention: Figure 1 is a sideelevation showingone of the coupling members partly placed in position upon the end of abelt, partly in section; Fig. 2 shows the cooperating member in asimilar position upon the other end of the belt, partly in section; Fig.3 is a perspective view showing one of the coupling members secured inposition upon the end of a belt and ready to be coupled to the other endof a belt having a like coupling 1nember secured thereto; Fig. 4 is aside elevation showing the coupling members secured upon the ends of thebelt and coupled to gether; Fig. 5 is a side elevation of a moth: tiedform of coupling member, the same being formed of a flat plate bent uponitself to form the curved hook and double jaw secured to the belt at oneside thereof; Fig.

6 is a side elevation showing two coupling members each formed of a fiatplate or jaw having integrally formed teeth adapted to engage a belt andsecure said jaw thereto and each having an integrally formed curved hookadapted to engage the curved hook of the other coupling member.

In the embodiment of my invention, as illustrated in Figs. 1 to finclusive, 1 represents a coupling member and 2 the cooperating couplingmember each of said coupling members being formed of flat sheet steel orother suitable material folded upon itself a portion of its length andcurved in said folded portion to form a curved hook or roll clutch 3 ofsubstantially spiral crosssection which is adapted to enter and re-Specification of Letters Patent.

ceive a like hook or roll clutch 3 of the other cooperating couplingmember. Each of said members is spread apart the remainder of its lengthto form clamping jaws at and 5 each of which is provided with integrallyformed pointed teeth (5 extending at an angle from the jaw and towardthe other jaw and each adapted to be driven into the end portion of thebelt 7 and clenched therein by the ends of said teeth striking theopposite jaw which serves as an anvil to turn said teeth into holdingengagement with the belt. Part of the teeth 6 are preferably stamped outofthe body of the plate or jaw and part are formed upon the edge thereofand said teeth of the respective jaws are preferably arranged instaggered form so as to enter said belt at (lill'crent points andthereby not conflict with each other. By projecting the outer or endteeth at an acute angle to the plate or jaw causes the points thereof toengage the under surface of the opposite plate or jaw and this causesthe ends of the teeth to turn and elcnch the belt. When the couplingmembers are formed, as shown in Figs. 1 and 2, they are secured to therespective ends of the belt 7 by first driving the teeth upon the edgethereof and said teeth of the belt as shown in Figs. 1 and 2 and thenbending the other jaw downwardly toward the belt and driving the teeththereof into the belt until the teeth are clenched therein in the mannershown in Fig. 3. After the coupling members are secured in position inthe manner shown in Fig. 3 they are connected together in the mannershown in Fig. 4 by simply sliding the hook portions endwise into eachother so that the outer gages the outer and inner surfaces,respectively, of the other hook and each bears snugly against the other,thus producing a clutch connection and preserving the flexiblecharacteristics of the belt.

It is apparent that my invention is capable of some modification withoutdeparture from the spirit or scope thereof, as shown by Fig. 5 in whichthe jaws 8 and 9 are folded upon each other and are adapted to be placedupon one side only of the belt and to have the teeth 6 extend into thebelt from only one side; or said members may be formed in the mannershown in F ig. (3 in which the coupling member 10 consists of a flatplate 11 having integrally formed teeth 6 adapted to be secured to thebelt 7 and having its free end curved to form a hook or roll clutch 13substantially as shown in Fig. 6.

My structure is exceedingly strong and durable and possesses all of themeritorious features requisite for a highly efficient detachable beltcoupling.

It will be noted that my coupling members can be very easily and cheaplyformed of sheet steel, each member being complete in a single piece andthat the same can be easily and quickly secured upon the end of the beltby any person at a moments notice by simply using a hammer, each pair ofcoupling members being placed so that the hook 3 of each member extendsin the reverse direction to the hook of the cooperating member so thatwhen the ends of the belt are brought together said hook members willinterei'igage each other to complete the formation of the belt.

Desirable features of my invention are neatness in appearance,compactness, cheapness in construction, simplicity and convenience inapplying, and durability in use.

An important feature of my invention consists in securing the teeth tothe belt extremely near its ends.

Another important. feature of my inven tion when constructed with doubleaws is that the teeth are curved and protected from injuring either themachinery or operators of the. machinery and there is no projecting orprotruding parts to cause said coupling members to become detached fromthe belt. As shown in the drawing, this form of cou-- pling member isadapted to be readily secured to belts of more than one ply.

The construction shown in Figs. 1 and 2 is specially adapted for heavybelts where great strength is essential. The forms of coupling shown inFigs. 5 and 6 are intended for lighter belts or when it is desired tostill further reduce the cost of construction.

It will be seen that my detachable coupling permits of the ready andconvenient connecting and disconnecting of the ends of the belt for thepurpose of placing it in position for use or removing it therefrom orfor turning or twisting it as may be desired.

If it should be desired to secure the coupling members 1 and 2 inposition upon the belt in such a manner that they may be removed andused over again in shortening the belt or upon new belts this may beaccomplished by forming the teeth 6 of shorter length so that they willnot strike the opposite jaw and clench inthe manner hereinbeforedescribed thus permitting the teeth 6 to be readily withdrawn from thebelt 7 and the jaws removed from the belt whereby said coupling membersmay be used over again.

I claim:

1. In a detachable belt coupling, the combinationof two substantiallyidentical in- Yersely presented coupling members, each comprising meansto be attached to a side of the belt near its end and comprising a hookof substantially spiral cross section with its axis running along theend of the belt, the hooks of the respective members receiving eachother, andtheir respective spiral cross sections precluding their radialor tangential displacement from each other, but said hooksbeing capableof swiveling movement in each other and of axial movement 1n each other,for the purposes set forth.

double thickness formed by continuations of said plates pressed closelytogether and bent into substantially spiral cross section with the axisof said cross section running along the end of the belt, said hooks ofthe two members interlocking.
